TI中文支持网Other Parts Discussed in Thread:BQ34Z100-G1, BQ27426
您好，我使用的电池是Sanyo NCR18650GA(3450mAh)，通过BQ34Z100-G1采集的数据，使用GPC工具获得的chemical ID推荐如下，下面也有Sanyo NCR18650GA的chemical ID 1580，但推荐的最佳ID是2348，对于BQ34Z100-G1来说我应该怎么选择哪个chemical ID？下面的警告是什么意思，是否可以忽略？

Star Xu：
您好，建议使用报告中推荐的最佳ID，max DOD error 在3%以内都可以使用。
warning推荐的ID max DOD error>10%不推荐使用，可以忽略。
